Much attention has recently been given to quantify the environmental and social importance on agricultural water quality impacts by agricultural activities. The demands for relevant data collection and range expansion of environmental indexing has been also higher than ever. Therefore, this study organized past and current research on agricultural water quality standards by OECD and Korea to evaluate agricultural activities and their impacts on agri-environmental policy development. The agricultural water quality standard set by OECD shows different opinions countries by counties, so the status indicator has been chosen and implemented instead. Nitrate (NO3 -) status indicator of groundwater in 2013 was significantly improved compared with the one in 2007. In addition, the quality status of surface water and groundwater were improved. It is necessary to set up a cooperative system between policy division and research institute to organizationally take action to worldwide trend on agricultural water quality indexing.

물 발자국 산정의 장점은 녹색, 청색, 회색 물을 포함한 다른 유형의 소비적인 물 사용을 측정하는 것이다. 그리고 물발자국은 특정 장소와 시간에 물 사용이 연결되는데, 이는 담수자원의 재생 가능성뿐 만 아니라, 이 기간 동안 지역에 물의 이용이 제한되기 때문에 물을 효율적으로 사용해야 한다는필요성을 강조한다. 물 부족에 대한 정보를 함께 사용한다면발자국은 더 많은 정보를 제공할 수 있게 된다. 예를 들어,충청북도와 강원도에서 자라는 벼를 비교해 보면 총 물 발자국은 거의 동일하지만 1인당 신재생 담수량은 강원도가 훨씬낮다. 이와 같이 한 시스템에서 수문 지속성을 평가하기 위해물 발자국을 사용하는 것은 중요한 일이다. 결론적으로 서로다른 값의 물 발자국 분리는 물 발자국 산정에서 중요한 부분이기 때문에 항상 강수의 소비적인 사용(녹색 물 사용)과 지하수 혹은 지표수의 소비적인 사용(청색 물 사용)의 차이를 만들어야 한다.

Light is a energy source for photosynthesis og green plant and sources for photoperiodsm and photomorphogenesis. Plants have showed a variety of reactions corresponding to the surrounding environment to survive, and have introduced environmental signal into growth development. Rice yield has reduced by increasing localized heavy rain that leads duration of solar intensity to decrease 10-16% during cultivation period. It is necessary to improve adaptive technology and observe change of rice yield and growth by decrease of solar intensity for safe culture of rice. For these reasos, we carried out shade culture experiment and compared to rice growth and yield for two rice varity(Dasanbyeo, Chuchengbyeo) in 2008, and we also performed shade culture experiment at two growth stage(panicle formation stage, booting stage) in order to research rice growth and yield by decease of solar intensity on 2009. We carried out shade treatment to make different solar intensity under three different conditions; control, 30-40% block, 70-80% block using shade net. As a result, experiment result showed that plant height and SPAD value were more inceased and tiller number was more deceased under shade treatment than control. Shade treatment decreased rice yield by reducing panicles number per m2 spikelet number per panicle, and percent ripened grain of yield component. The results of protein analysis showed difference between control and treatment.
